Description
Stand der TechnikState of the art
Die vorliegende Erfindung betrifft ein Fahrrad mit einem Kardanantrieb und einem Elektromotor.The present invention relates to a bicycle with a cardan drive and an electric motor.
Fahrräder mit einem Kardanantrieb sind aus dem Stand der Technik in unterschiedlichen Ausgestaltungen bekannt, wobei sich Kardanantriebe durch ihre Leichtgängigkeit und Geräuscharmut auszeichnen.Bicycles with a cardan drive are known from the prior art in different configurations, with cardan drives are characterized by their ease and low noise.
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird ein Fahrrad bereitgestellt, das einen Kardanantrieb zur Drehmomentübertragung und einen Elektromotor zur Antriebskraftunterstützung umfasst. Hierbei sind der Kurbeltrieb und der Elektromotor mit dem Kardanantrieb verbunden. Das Fahrrad mit elektrisch unterstütztem Kardantrieb weist ein geringes Gewicht sowie einen leichtgängigen, robusten und wartungsfreundlichen Aufbau auf und ist kostengünstig herstellbar. Ein Abtrieb eines Drehmoments des Elektromotors kann somit ohne große Verluste über den Kardanantrieb erfolgen.According to the invention, a bicycle is provided which comprises a shaft drive for transmitting torque and an electric motor for driving force assistance. Here, the crank mechanism and the electric motor are connected to the shaft drive. The bicycle with electrically supported cardan drive has a low weight and a smooth, robust and easy to maintain construction and is inexpensive to produce. An output of a torque of the electric motor can thus be done without major losses on the shaft drive.
Die Unteransprüche zeigen bevorzugte Weiterbildungen der Erfindung.The dependent claims show preferred developments of the invention.
Gemäß einer bevorzugten Ausgestaltung der Erfindung bildet eine Kardanwelle des Kardanantriebs einen Rotor des Elektromotors. Hierdurch wird eine Reduzierung der Bauteile sowie des Bauvolumens und des Gewichts erreicht. Durch die große Baulänge des Rotors können zudem hohe Antriebsmomente bei relativ geringem Außendurchmesser des Elektromotors überfragen werden.According to a preferred embodiment of the invention, a cardan shaft of the cardan drive forms a rotor of the electric motor. As a result, a reduction of the components and the overall volume and weight is achieved. Due to the large length of the rotor also high drive torques can be asked with relatively small outer diameter of the electric motor.
Hierdurch kann eine besonders vorteilhafte Kombination eines Elektromotors mit einem Kardanantrieb realisiert werden.In this way, a particularly advantageous combination of an electric motor can be realized with a shaft drive.
Vorzugsweise sind an der Kardanwelle ein Antriebszahnrad zur Aufnahme eines Antriebsmoments vom Kurbeltrieb und ein Abtriebszahnrad zur Abgabe eines Abtriebsmoments an ein Hinterrad befestigt. Durch eine große Übersetzung zwischen dem Kurbeltrieb und dem Antriebszahnrad der Kardanwelle und eine entsprechend große Untersetzung zwischen dem Abtriebszahnrad der Kardanwelle und einem Ritzel des Hinterrads wird eine hohe Drehzahl der Kardanwelle bzw. des Rotors erreicht, so dass der Elektromotor mit geringer Masse ausgelegt werden kann. Dies trägt wesentlich zu einer Gesamt-Gewichtsreduzierung des Fahrrads bei.Preferably, a drive gear for receiving a drive torque from the crank mechanism and a driven gear for outputting a driven torque to a rear wheel are attached to the propeller shaft. By a large ratio between the crank mechanism and the drive gear of the propeller shaft and a correspondingly large reduction between the output gear of the propeller shaft and a pinion of the rear wheel, a high speed of the propeller shaft or the rotor is achieved, so that the electric motor can be designed with low mass. This contributes significantly to an overall weight reduction of the bicycle.
Ferner bevorzugt umfasst der Kardanantrieb ein auf der Kardanwelle angeordnetes Fahrradschaltgetriebe. Durch die Integration des Fahrradschaltgetriebes in das Gehäuse des Kardanantriebs wird eine äußerst kompakte Bauform erreicht und das Fahrradschaltgetriebe vor Verschmutzung geschützt. Bei einer elektromechanischen Betätigung des Fahrradschaltgetriebes kann zudem ein dazu erforderlicher Verkabelungsaufwand entfallen und eine einfache Steuerung des elektromechanischen Fahrradschaltgetriebes in Verbindung mit dem Elektromotor realisiert werden.Further preferably, the cardan drive comprises a arranged on the propeller shaft bicycle transmission. The integration of the bicycle transmission in the housing of the cardan drive an extremely compact design is achieved and protects the bicycle transmission from contamination. In an electromechanical actuation of the bicycle transmission also a required wiring effort can be omitted and a simple control of the electromechanical bicycle transmission can be realized in conjunction with the electric motor.
Weiterhin bevorzugt ist das Fahrradschaltgetriebe alternativ an einer Nabe des Hinterrads angeordnet. Hierdurch wird die kostengünstige Verwendung von herkömmlichen Schaltgetrieben ermöglicht und eine besonders einfache und kompakte Bauform erreicht.Further preferably, the bicycle transmission is alternatively disposed on a hub of the rear wheel. As a result, the cost-effective use of conventional manual transmissions is made possible and achieved a particularly simple and compact design.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist das Gehäuse des Elektromotors als Querstrebe für das Hinterrad ausgebildet. Hierdurch kann der Kardanantrieb auf einfache Weise in den Rahmen des Fahrrads integriert werden. Durch die schlanke Bauform wird ein attraktives und gleichzeitig unauffälliges Design erreicht, das im Wesentlichen einem konventionellen Fahrrad gleicht. Dies ermöglicht eine unsichtbare Integration des Elektromotors in das Fahrrad.In a further advantageous embodiment of the invention, the housing of the electric motor is designed as a transverse strut for the rear wheel. As a result, the shaft drive can be easily integrated into the frame of the bicycle. The slim design achieves an attractive and at the same time inconspicuous design, which is essentially similar to a conventional bicycle. This allows an invisible integration of the electric motor in the bike.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Elektromotor parallel zum Kardanantrieb angeordnet, wobei der Elektromotor über eine Drehmomentübertragungseinrichtung mit der Kardanwelle verbunden ist. Durch die achsparallele Anordnung des Elektromotors und eine entsprechende Übersetzung der Drehmomentübertragungseinrichtung ist eine zusätzliche Erhöhung der Drehzahl des Elektromotors realisierbar, sodass dieser mit einer entsprechend reduzierten Masse ausgelegt sein kann. Außerdem wird dadurch auf einfache Weise ein Austausch des Elektromotors ermöglicht.According to a preferred embodiment of the invention, the electric motor is arranged parallel to the shaft drive, wherein the electric motor is connected via a torque transmission device with the propeller shaft. Due to the axis-parallel arrangement of the electric motor and a corresponding translation of the torque transmission device, an additional increase in the speed of the electric motor can be realized, so that it can be designed with a correspondingly reduced mass. In addition, a replacement of the electric motor is made possible in a simple manner.
Vorzugsweise umfasst die Drehmomentübertragungseinrichtung ein oder mehrere Zahnradpaare oder einen Riemenantrieb. Hierdurch wird eine kompakte, betriebssichere und wartungsfreundliche Drehmomentübertragung zum Kardanantrieb erreicht. Ferner kann die erforderliche Übersetzung auf einfache Weise angepasst bzw. geändert werden.Preferably, the torque transmitting device comprises one or more gear pairs or a belt drive. As a result, a compact, reliable and easy to maintain torque transmission is achieved for the cardan drive. Furthermore, the required translation can be easily adapted or changed.
Weiterhin bevorzugt weist das Fahrrad eine Rücktrittbremse auf. Die Verwendung einer handelsüblichen Rücktrittbremse in Verbindung mit dem Kardanantrieb trägt zur einfachen und kostengünstigen Bauweise des Fahrrads bei. Außerdem kann durch die Betätigung der Rücktrittbremse eine automatische Abschaltung des Elektromotors erfolgen, was wesentlich zur Betriebs- und Verkehrsicherheit des Fahrrads beiträgt.Further preferably, the bicycle has a coaster brake. The use of a commercial coaster brake in conjunction with the propeller drive contributes to the simple and inexpensive construction of the bike. In addition, an automatic shutdown of the electric motor can be done by the operation of the coaster brake, which contributes significantly to the operational and safety of the bicycle.
